For that you’ll need a true random number generator (RNG), and this open-source hardware RNG uses one of the better methods we’ve seen. The device, called RAVA, is based on a property found in ...

Admittedly, the SB42 Random Number Generator built by [Simon Boak] isn’t exactly something you’d be using for cryptography. The method used to generate the digits, a pair of 555 timers sending ...

Lasers can generate random number sequences thanks to tiny, naturally occurring fluctuations in the light’s frequency over time. But using a laser beam to produce random numbers like that is ...
